3 Claims.

This invention relates to traverse motions for spinning frames, twisterframes and the like, and more especially to an improved driving meansfor the builder cam.

Heretofore, the builder cam associated with the builder motion, which isa part of a traverse motion, on a spinning frame or the like has beendriven through a series of gears including beveled gears and a worm andworm gear drive combination, the worm gear being fixed on the shaft onwhich the builder cam has been fixedly mounted. It is well known that acertain amount of back-lash is essential in beveled gears and in wormand worm gear drives and that the socalled pitman roll which ridesagainst the builder cam has lifting effect against the builder cam asthe high point of the cam moves toward and into engagement with thepitman roll.

On the other hand, immediately upon the high point of the cam moving outof engagement with the pitman roll, the builder motion is relieved,momentarily, of the weight of the ring rail and intervening parts andfalls, by gravity, thus momentarily reversing the pressure on thebeveled gears and the worm and worm gear combination. The ring rail willthen remain stationary until any back-lash in these gears is overcome.

When the ring rail remains stationary, several rounds of yarn may be fedto the bobbins at a single point along their lengths. Now, when the yarnis withdrawn from these bobbins, such as on a winding machine or in theshuttle of a loom, several rounds of yarn may be withdrawn from thebobbins simultaneously as a result of these several rounds being formedby a momentary :1.

pause of the ring rail, and these rounds would become entangled andbreak or cause a defect in the fabric being woven or the packages ofyarn being wound.

It is therefore an object of this invention to provide an improved chaindrive mechanism for spinning frames and the like for transmittingrotation to the builder motion cam, the chain employed preferably beinga silent type of chain,

and through a series of chain and sprocket com a binations reducing therate of speed transmitted from the usual driving source of the spinningframe to obtain the same rate of speed of the builder cam as hasheretofore been the case, without the necessity of using beveled gearsor a worm and worm gear drive combination thus eliminating the back-lashwhich has heretofore resulted in the diinculties previously described.

It is another object of this invention to provide a combination spurgear and chain drive for transmitting rotation from the main cylindershaft of the spinning frame, twister o the like to the builder motioncam, to not only avoid the occurrence of back-lash through theintervening connections but to also provide means for varying the speedof the builder motion cam relative to the speed of the bobbins byutilizing at least one of the spur gears as a change-gear. The purposeof varying the speed of the builder motion cam is to vary the speed atwhich the ring rail traverses, in a vertical plane, past the bobbinsrelative to the speed at which rotation is imparted to the bobbins tocontrol the number of rounds fed to the bobbins in a predeterminedlength of the bobbins.

Some of the objects of the invention having been stated, other objectswill appear as the description proceeds when taken in connection withthe accompanying drawings in Which- Figure 1 is an end elevation lookingat the head end of a spinning frame with the usual cover thereforremoved and showing the improved chain drive mechanism for driving thebuilder motion cam;

Figure 6 is an enlarged elevation of the builder motion lookingsubstantially along the line *6'6 in Figure 5;

Figure '7 is a fragmentary elevation looking at the opposite side of thebuilder motion shown in Figure 5 and showing the pitman roll engagingthe builder cam.

Referring more specifically to the'drawings the numeral Ill indicates ahead end member of a spinning frame or the like to which one end of amain bottom rail H and one end of a-bolster ll having whorls thereonover which a suitable belt 2| is mounted, the belt being also mounted ona centrally disposed main cylinder 22 which is fixed on a main driveshaft 23. The shaft 23 is driven in a conventional manner by means, notshown, disposed at the other end of the spinning frame from that shownin Figure 5.

The spinning frame has a conventional ring rail 25 having a plurality ofrings 26 thereon and each ring having a traveler 21 mounted thereonthrough which the strands S pass to the bobbins l6 as the ring rail 25reciprocates in a vertical plane by means of the usual builder motion tobe presently described.

The ring rail 25 is supported at various points throughout its length ona plurality of conventional lifter rods 30, only one of which is shownin Figure 5. This lifter rod 30 slidably penetrates the bolster rail I2and the bottom rail H and the lower end thereof has a shoe 3| fixedlymounted thereon which bears against a roller 32 rotatably mounted on astub 33 in a conventional lifter arm 34.

The lifter arm 34 is oscillatably mounted intermediate its ends, as at35, on a conventional bearing hanger 36 secured, as by screws 37, to thebottom rail ll of the spinning frame. This conventional lifter arm 34has a weight member 4|] at its right hand end in Figure 5, or at its endremote from the roller 32, and also has an upwardly extending portion 4|integral therewith which has secured thereto, as by screws 52, aconventional chain are 43.

The upper end of the upwardly extending portion 4| of the lifter arm 34has pivotally connected thereto one end of an extension rod 44 whichextends to similar lifter arms, not shown, for transmitting movement tothe other conventional lifter rods, not shown, like the lifter rod 30 inFigure l.

The chain are 43, which is often referred to as quadrant, has one end ofa conventional builder chain 45 connected thereto. This builder chain 46extends over a conventional pulley 6T, rotatably mounted in a bracket5|] secured, as by screws 5|, to the head end frame member Hi. Thebuilder chain 46 extends downwardly from the pulley 41 and is connectedat the lower end thereof to a hook member 52 of a conventional buildermotion broadly designated at 53. There are various types of buildermotions in use such as a bunch builder, a combination builder or afilling builder and these builder motions are slightly different fromeach other in construction and employ various shapes of builder cams.The builder motion 53 shown in Figures 5, 6 and 7 is of the typegenerally referred to as a bunch builder,.but it is to be understoodthat the present invention will work equally as well with various typesof builder motions and will greatly improve the operation of all threeof the types of builder motions heretofore described.

The particular type of builder motion 53 shown in Figures 5, 6 and '7includes a lever 54 oscillatably mounted intermediate its ends as at 55,on a bracket 56 secured, as by screws 51, to the head frame member Ill.This lever 54 is irregular in shape at one end thereof and has a weightmember 6|! at the other end thereof. The irregularly shaped end of thelever 54 has a conventional worm shaft 5| rotatably mounted therein onwhich a worm 62 is fixedly mounted. The worm shaft 6| extends throughthe end of the lever 54 and has a conventional ratchet wheel 63 fixedlymounted thereon. This ratchet wheel 63 is adapted to engage a ratchetpawl 64 pivotally mounted in a bracket 55 secured, as by screws 66, tothe head end frame member l5. This pivoted ratchet pawl 64 engages theratchet wheel 53 upon each downward stroke of the lefthand end of thelever 54 in Figure 6, and transmits a step in rotation to the shaft 5|upon each upward stroke of the left-hand end of the lever 54 in Figure6.

The means for transmitting vertical movement to the lever 54 includes apitman roll 61 rotatably mounted in a downwardly projecting portion 10of the lever 54 (Figures 5 and 7). A conventional builder motion cam 7|,which is shown as a four lobe cam but which may be of any desired shapesuch as a heart-shaped cam, is engaged by the pitman roll 67. The pitmanroll 51 is urged against the periphery of the builder motion cam 1| dueto the weight member St at the other end of the lever 54.

The worm 52 on the shaft 6| engages a rack '12 secured to a dove-tailedslide member 13 and upon step-by-step rotation being imparted to theconventional worm 62, like movement will be transmitted to the rack 12so as to transmit stepby-step movement to the dove-tailed slide member13, to which the hook member 52 is pivotally connected, for graduallychanging the range of vertical movement of the ring rail in aconventional manner. The dove-tailed slide member i3 is mounted forsliding movement in the lefthand end of the lever 54 in Figure 6.

The builder motion cam 1| is fixedly mounted on one end of a builder camshaft which extends through and is rotatably mounted in the head endframe member ID and has a sprocket wheel 16 fixedly mounted on its endremote from the cam 1| and within the head end frame member ID. Thissprocket wheel 16 is a part of the present invention, relating to meansfor transmitting positive rotation to the shaft 15 on which the buildermotion cam 1| is fixedly mounted.

Heretofore, a worm gear has been employed in lieu of the sprocket wheel16 and has been driven through a worm and a series of gears, including apair of beveled gears, and the primary object of this invention is toeliminate the use of beveled gears in the course of transmittingrotation to the cam shaft 75 from the main cylinder shaft 23 shown inthe central portion of Figure 1. The purpose of eliminating the beveledgears will be later described in summarizing the operation of thisapparatus.

Most of the parts of the conventional driving mechanism for the spinningframe or the like are retained in the head end frame member 10 andoperate in conjunction with the present invention and these partsinclude a twist spur gear Tl rotatably mounted on a stub shaft 18projecting from and fixedly mounted in the head end frame member Hi.This twist gear Ti is driven in a manner to be presently described andimparts rotation to a left-hand interim gear 8| which, in turn,transmits rotation to a right-hand interim gear 82, these interim gears8| and 82 are spur gears and are rotatably mounted on stub shafts 83 and34, respectively, fixedly mounted in the head end frame member H]. Thestub shaft 83 is conventional, and the stub shaft 84 is especiallyadapted to the present invention and will be later described in detail.

The interim gears 8| and 82 transmit rotation to front roll shafts and9| through gears 92 and 93, respectively, rotatably mounted on stubshafts 94 and 95 fixedly mounted in and projecting from the head endframe member I6. The gears 92 and 93 have pinions 96 and 91 fixedthereto, in a conventional manner, which, in turn, mesh with gears 98and 99, respectively, fixedly mounted on the top roll shafts 96 and 9|respectively. This completes the description of the conventional gearingdisposed within the head frame member ID.

Now, fixedly mounted on the main cylinder shaft 23 is a sprocket wheelI65 on which a sprocket chain I66 is mounted. This sprocket chain I66 isalso mounted on a sprocket wheel I61 rotatably mounted on the stub shaft18 and having the twist gear.11 secured thereto. Thus, rotation istransmitted from the shaft 23 through the sprocket wheels I65 and I81,and the sprocket chain I66, to the twist gear 11 which, in turn,transmits rotation to the interim gears 8| and 62.

The right-hand interim gear 82 (Figure 1) is rotatably mounted on thestub shaft 84 as heretofore described. Now, this stub shaft 84, as shownin detail in Figures 3 and 4, has an enlarged portion IIB integraltherewith and a restricted threaded portion I I I, this restrictedthreaded portion I II having flats I I2 on opposed sides thereof (Figure4). The head end frame member has a vertically extending slot I I3therein which is slidably penetrated by the restricted threaded portionI I I of the stub shaft 84 and the flats of the restricted threadedportion IIi prevent the stub shaft 84 from rotating in the slot H3.

The outer end of the restricted threaded portion II I has a washer II 5mounted thereon against which a nut H6 is driven home on the threadedend of the restricted portion II I. A suitable oil cup I I1 isthreadably mounted in one end of the stub shaft 84 and the stub shafthas communicating passageways I20, I2I and I22 therein for directinglubricant from the oil cup I 11 to the interim gear 82 as well as to asprocket wheel I23 which is also rotatably mounted on the stub shaft 84and which is suitably secured to the interim gear 82 so that rotation ofthe interim gear 82 will cause like rotation to be imparted to thesprocket wheel I23.

The enlarged portion III) of the stub shaft 84 has the forked end I25 ofa change gear bracket, broadly designated at I2'6, loosely mountedthereon (Figure 4). This change gear bracket I26 has a substantiallyU-shaped portion I21 (Figure 3) integral with its end remote from thestub shaft 84 and in which a stub shaft I36 is rotatably mounted. Keyedon the stub shaft I66, as by a Woodruff key I3 I, is a sprocket wheelI32 which is disposed between the legs of the U-shaped portion I21 andhas a sprocket chain I33 mounted thereon, this sprocket chain I33 alsobeing mounted on the sprocket wheel I23 so as to transmit rotation fromthe sprocket wheel I23 to the sprocket wheel I32 and the shaft I 30.

The end of the change gear bracket I26 forming the wall of the U-shapedmember I21 adjacent the head end frame Ill has extended wing portionsI34 and I35 provided with a curved slot which extends from adjacent oneend of the wing portion I34 to adjacent the remote end of the wingportion I 35.

curved slot I36 is slidably penetrated by a bolt I31 for securing thechange gear bracket I26 in adjusted position depending upon the size ofchange gear mounted thereon.

A spur change gear I46 is keyed to a restricted end portion I4I of thestub shaft I36 and is se- The radius point of this curved slot I86 isthe center of the stub shaft 84 and this cured thereon by any suitablemeans such as a cap screw I42 threadably embedded in the free end of therestricted portion I4I. This change gear meshes with a second spurchange gear I45 which is commonly known as a lay compound gear. The laycompound gear I45 is keyed to a restricted end portion I46 of a stubshaft I41 and is secured thereon as by a screw I50 (Figure 2). This stubshaft I41 is rotatably mounted in the forked upper end I5I of animprovedtraverse motion drive bracket broadly designated at I52. Thebuilder motion drive bracket I52 and the change gear bracket I26 areessential parts of the present invention and they are designed in such amanner as to eliminate many of the gears and other parts heretoforerequired in driving the usual types of traverse motions. The traversemotion drive bracket I52 is secured, as by square shanked bolts I53, I54and I55 to the head end frame member Ill. The lower end of the buildermotion bracket I52 has an enlarged portion I55a provided with a slotI552) which is penetrated by the screw I55 for purposes to be laterdescribed.

A sprocket wheel I51 is fixedly mounted on a restricted portion I66 ofthe stub shaft I41 and is keyed thereto, as by a Woodruif key I6I, andis secured thereon as by a set screw I62. The sprocket wheel :51, whichis a relatively small sprocket wheel, has a sprocket chain I63preferably'of the silent type, mounted thereon, this sprocket chain I63is also mounted on a relatively large intermediate sprocket wheel I64.The sprocket wheel I 64 is fixedly mounted, as by a set screw 565(Figure 2) and a key I'66, on the hub of a relatively small intermediatesprocket Wheel I531. The small sprocket wheel I61 is rotatably mountedon a sleeve I10 which is slidably mounted on a restricted portion I1I ofa stub shaft I 12. The stub shaft I 12 has a head portion I13 at one endthereof.

It will be observed in Figure 1 that the builder motion drive bracketI52 has an enlarged cen-. tral portion I14 integral therewith having atransverse slot I 15 therein. This transverse slot I16 is slidablypenetrated by the stub shaft I12, this stub shaft being secured in theslot I16 by a lock nut I11 threadably mounted on a restricted threadedportion I86 of the stub shaft I12, this restricted threaded portion I86being of slightly large diameter than the restricted portion I1I onwhich the sleeve I10 is mounted. The purpose of the slot I16 is toprovide means for taking the slack out of the sprocket chains mounted onthe various sprocket wheels on the bracket I 52. The left-hand end ofthe stub shaft I12, in Figure 2, has a nut I 62 threadably mountedthereon for securing the sleeve I16 against the shoulder formed by therestricted threaded portion I86. It is thus seen that the intermedi atesprocket wheels I64 and I61 may rotate on the sleeve I16.

The small intermediate sprocket wheel I61 has a sprocket chain I83mounted thereon which extends downwardly and which is also mounted on arelatively large lower sprocket wheel I84 fixedly mounted on a lowerstub shaft I85, as by a set screw I86 and a Woodrufi key I 81. The stubshaft I (Figure 2) is mounted in a thickened or raised portion I 58integral with the lower portion of the builder motion drive bracket I52.This raised or thickened portion I96 has an opening I93 therein which isalso spanned by the stub shaft I85, and disposed within the opening I93and fixed on the shaft I85, as by a set screw I94 and a key I95, is arelatively small lower sprocket wheel I96. This sprocket wheel I96 has asprocket chain 2Il|l mounted thereon which is also mounted on thesprocket wheel I6 heretofore described as being mounted on the rotatablecam shaft I5. The stub shafts 84, I3fi, I47, H2 and I85 are all providedwith suitable friction bearings which are a usual part of structures ofthis type and a detailed description thereof is deemed unnecessary.

In mounting the traverse motion drive bracket I52 on the head memberIII, the bracket I52 is first pivotally secured to the head member byeither of the bolts I53, I54 and also by the bolt I55 penetrating theadjustment slot I551). The chain 200 is then mounted on the sprocketwheels I6 and I96 and the bracket I52 is adjusted to take up any slackin the chain 200. The hole I53a or I540: is then drilled in the headframe member ID for reception of the bolt I53 or I54, which may havebeen previously omitted, and the bolt I53 or I54 is tightened to holdthe bracket I52 in adjusted position. All the sprocket chains shown inFigure 1 must be taut in order to prevent occurrence of back-lash in thetraverse motion drive.

It is thus seen that rotation will be transmitted from the right-handinterim gear 82 to the sprocket wheel I23 and successively through thesprocket chain I33, the sprocket wheel I32,

the change gear I42, the lay compound gear I45,

the sprocket wheel I51, the sprocket chain I63, the sprocket wheel I64,and thus to the sprocket wheel IE1 which rotates with the sprocket wheelI64. The sprocket wheel IG'I, in turn, transmits rotation to thesprocket wheel I54 through the H sprocket chain I83. The sprocket wheelI84 fixedly mounted on the stub shaft I85 transmits rotation to thesmall sprocket wheel I96 which, in turn, transmits rotation to thesprocket wheel I6 through the sprocket chain 200 to thus drive the camshaft and the builder motion cam II (Figures 6 and 7).

It is well known, to those familiar with the art, that the buildermotion cam II must rotate at a very slow rate in comparison to the rateof ro- .5

Now, in operation, the pitman roll 67 is urged against the periphery ofthe cam wheel II by the weight member 65 and, as the pitman roll 6!moves to the low points in the cam wheel H,

the left-hand end of the lever 54 moves upwardly thus permitting thechain are 43 to move from left to right in Figure 4 by virtue of theweight 43on the lifter arm 34. This will, of course, permit the roller32 to move upwardly, with the arm 34, to elevate the ring rail throughthe medium of the lifter rod 39 Now, it is evident that during thislifting action of the lifter arm 34 and the lever 54, the builder cam iIwould exert very little resistance against the upward movement of thepitman roll 51 since the weights 55 and 68 act to facilitate this upwardmovement.

Upon the cam II moving so the pitman roll 61 moves toward the high pointof the builder cam I I, the pressure exerted by the roll 51 against thecam II is increased due to the fact that the cam II must force theleft-hand end of the lever 54 downwardly and, in so doing, must alsoforce the builder chain 46 downwardly and must raise the weights 40 andB5. The improved driving means will cause the builder motion to operateevenly regardless of this reversal of pressure.

However, if the conventional type of drive apparatus were employed intransmitting rotation to the builder cam I I, pressure between thedriving and the driven beveled gears, which are usual parts of the typesof traverse motion drives heretofore in use, would be exerted in onedirection during the time that the pitman roll 61 was lowered in Figures6 and 7, from the low point of the builder motion cam II to the highpoint thereof and this pressure would be reversed as the pitman roll 61moved away from the high point of the cam II and to the low point of thebuilder motion cam II. It is evident that, heretofore, this caused acertain amount of back-lash between the beveled gears as the pitman roll67 moved away from the apex of the high point of the builder motion camII and, momentarily, this back-lash would have to be overcome betweenthe two beveled gears heretofore employed and, during this interim, thering rail 25 would remain stationary with the result that several roundsof yarn S would be applied to the bobbins I6 at one point along thelength thereof. This would result in a faulty package, because whereverthere were several rounds placed on a bobbin at a single point, all ofthese rounds would likely b withdrawn simultaneously from the bobbin infuture operations, such as in the shuttle of a loom or in a winder orthe like, and these several rounds of yarn would become knotted orentangled and this would result in an inferior material being woven onthe loom or in an inferior package being wound on the winding machine,or it would cause the yarn to break thus requiring the ends to be piecedtogether and resulting in additional cost in future yarn processingoperations.

It is thus seen that the improved driving means will overcome thisback-lash and will cause the builder motion to operate in an even mannerand will provide a more positive control of the same.

In the drawings and specification there has been set forth a preferredembodiment of the invention and although specific terms are employed,they are used in a generic and descriptive sense only, and not forpurposes of limitation, the scope of the invention being defined in theclaims.
